FIELD OF THE INVENTION

The present invention generally relates to a scarf. More specifically, to a multifunctional heated scarf that provides strategically positioned compartments utilized for housing heating devices and frequently manipulated items in cold weather environments.

BACKGROUND OF THE INVENTION

It is well known that scarves are used as a means to protect a user's head and neck from heat loss in cold weather environments. Typically, scarves are constructed from natural or synthetic fibers woven into a rectangular piece of linen. Compared to other cold weather accessories such as ski masks, neck wraps, or ear muffs, scarves are versatile and can be adapted to protect the user's face or neck depending on their preference. Generally, scarves are wrapped around the user's neck or face in loosely packed layers that insulate body warmth while protecting the user's skin from exposure to cold temperatures. While traditional scarves offer adequate protection to a user's face and neck, they only retain body heat and are limited by the user's base body temperature. This limitation is most evident in colder environments where heat is lost rapidly.

Although traditional scarves function primarily as an insulating barrier, newer configurations have been developed that utilize integrated heat sources. These newer scarves insulate a user's body heat and actively warm the user, reducing net heat loss in colder environments. These heated scarves are generally constructed with either an electrical or chemical heating elements. Electrically heated scarves offer users with the advantage of a controlled heat source that can be activated and deactivated at will, but suffer from the disadvantage of requiring an electrical source in order to function. Chemically heated scarves utilize an air activated chemical composition that undergoes an exothermic reaction when exposed to ambient oxygen. Unlike electrical heating elements, the air activated chemical composition only requires exposure to ambient oxygen to activate and begin heating up. While chemically heated scarves are functionally limited by presence of the air activated chemical composition, they are able reach their desired operating temperature faster and provide consistent heat for longer periods of time compared to electrically heated scarves.

Although chemically heated scarves provide several advantages over their electrical counter parts, existing configurations lack safe and adequate means to evenly distribute heat. In part most existing chemically heated scarves utilize a single compartment for retaining the air activated heating element. This single compartment would house a single large heating element, centrally aligned along the length of the scarf. This design limits the distribution of heat but additionally makes it difficult for a user to deactivate the heat source without removing their scarf.

It is therefore the object of the present invention to provide a multifunctional heated scarf that is able to evenly distribute heat from a plurality of air activated heating elements. The present invention accomplishes this through the integration of a plurality of compartments strategically distributed along the length of the scarf. The plurality of compartments enable improved distribution of the air activated heating elements while allowing a user to easily remove or reposition said air heating elements with ease. The present invention additionally provides compartments positioned at the extremities of the scarf that allow for rapid storage and retrieval of frequently manipulated items.
